iOS/Android: Adobe released its Photoshop Touch app for smartphones today. The app has the same basic features as the iPad and Android tablet apps released last year, including layers, fills, selection tools, and plenty more.

Photoshop Touch works surprisingly well on the smaller touch screen. You can edit photos, crop, and retouch. You can also do standard cloning, brush, and effects. Unique to the smartphone version is a new "Scribble Selection" tool that lets you quickly combine images together, including a live view using your phone's camera. If you're a desktop and tablet user, Photoshop Touch also syncs with the Adobe Creative Cloud so your work is synced across devices. The iPhone version requires an iPhone 4S or fifth-generation iPod Touch or newer.
